Two-Step Verification (Duo)

A number of Cal Poly tech services, including Virtual Computer Labs (AppStream), Common Management System (CMS), Virtual Private Network (VPN) and LastPass, require verification of identity via two-step verification. Duo is a two-step verification app that allows students, faculty and staff to authenticate their identity in two ways—with something they know (username and password) and something they have (mobile device or telephone). Two-step verification, also referred to as two-factor authentication (2FA) or multi-factor authentication (MFA), protects sensitive information by strengthening the security of the login process.
